Unfortunately, a lot of the things one usually does to prevent moire in camera are not adjustable on the Skidio. I assume you're shooting in 4k? It's usually worse in the higher resolutions.
Have you tried using an ND filter. An ND might help. Maybe even a Polarized filter. I used a Polarized filter back when I was using my Hero 4 black and really liked the results.
A lot of editors like Lightroom have a moire filter/adjustment for reducing it in post.
